I've been a heavy Visine user for years, but lately I've noticed that if I don't use Visine, my eyes are always red, sober or stoned. Not good, so I decided to try Clear Eyes for dry eyes, considering I spend a lot of time staring at a computer w/out blinking. Holy god do these fuck with my eyes, it makes them feel like I've been staring at a heater running full blast in my face. And they blur my vision something terrible for at least 45 minutes, so bad that after I blink, I can't read or make out faces until I blink about 10 more times and really try to focus my eyes. Just my fucked up eye drop story, didn't mean to go this long.
